Well no, TIDI had to be added in. It's purposefully slowing down in-game ticks.

Normally your requests would just be dropped if it had to process everything within a 1s tick. Now all reload times etc get slowed down by a huge factor depending on load.

Exactly. It was not something that happened automatically (not would it in almost any architecture). Instead the game would either cease to function properly or players would get disconnected or the server would crash, usually all of those in roughly that order. With TiDi at least things can happen, albeit at a frustratingly glacial pace.
